Sovol SV06 Belt Mounted Y-axis Sensorless Homing Stopper

What's the Purpose of This Part?

When the bed homes (Y-axis), it slightly twists along the X-Y plane when the bump occurs at the back. This is not an issue, that is, it's not having an effect on the printing process or print quality. However, this twisting shouldn't be happening in principle. This part prevents that twist from happening.

Some people seem to be concerned about damage occurring from this twist (mentioned above), but I see no evidence for that.

I actually would recommend against using this part (or any ancillary part that is mounted onto the belt) even though I was very thoughtful during the design process.

• There is a danger that this part (or similar) will spin as the bed moves back and forth, and could collide with the bed undercarriage. This might be very unlikely, but the possibility exists. Maybe I'll change my mind about this danger after more testing.

But the part is here if you need it. It's very easy to mount onto the belt, and holds on quite securely without damaging the belt.

BOM

• 2 x M3 socket head cap screws; 5mm to 8mm in length, but other sizes will also work.

Print Settings

• Print parts are oriented.
• No supports.
• I recommend PETG/ABS (maybe PLA+ is okay?).

Preparation

• Optionally sand the under piece top layer (the last layer to print) to ensure that the 2 pieces sit flush with each other.

Tools

• You need an M3 tap to tap the holes in the under.3mf piece.
• I also added an under-tapless.3mf that you can just screw an M3 bolt into.
